Title: "Photoresponse of ferroelectric BaTiO3 thin films"

Abstract: The main objective of this thesis is to understand photoelectric effects on nanometric BaTiO3 thin film and give light on relevant mechanisms that control them, aiming to build a more comprehensive understanding of its properties and to guide potential applications. Photoelectric effects studied in this thesis mainly refer to short-circuit photocurrents (Jsc) and the effect of light on polarization (P), focusing on the following aspects:

Influence of imprint Eimp and depolarization Edep fields on the photoresponse in BaTiO3 thin films.

Influence of microstructure and surface adsorbates on the photoresponse in BaTiO3 thin films.
